Although a malleable iron threaded pipe unions connects two pipes, it is quite different as compared to a coupling. This is because unions allows or has room for future disconnection of the pipes for maintenance. In contrast to a coupling requiring solvent welding, soldering, or rotation (generally meant for threaded couplings), a 3/4 malleable iron union allows the worker to easily connect and disconnect from the piping system. In fact a  2 malleable iron union permits the factory worker to connect and disconnect these unions multiple times if required. A union consists of three parts i.e. -  1. a nut, 2. a female end and  3. a male end. When the female and male ends of the black malleable iron unions are joined, the nut seals the joint by pressing the two ends together in a tight manner. Thus preventing them from coming undone. ASME B16.39 Union are a kind of very compact flange, which can be used as a connector.


A  1 black malleable iron insulated union is a type of serviceable connection which  incorporates a permanently moulded and bonded material. The incorporation of both these materials permits the malleable iron union 3/4 to act as an interruption point either in the metallic or a conductive path between a pipeline and its associated plant and /or equipment.

Dielectric malleable iron union elbow, with dielectric insulation tend to separate dissimilar metals such as copper and galvanized steel. This separation of metals helps to prevent galvanic corrosion. When two different metals come in contact with an electrically conductive solution for instance, tap water (ordinarily tap water is considered to be conductive), they form an electrochemical couple. As a result it generates a voltage by electrolysis. When the metals are in direct contact with each other, the electric current not only passes from one metal to the other, but also moves metallic ions from one to the other. During this phase, there is a dissolution of one metal, with the same getting deposited on the other. A dielectric malleable iron union with brass seat breaks the electrical path with a plastic liner that has been placed between its halves, thereby limiting galvanic corrosion.

Rotary Malleable Iron Union Dimensions allow mechanical rotation of one of their joined parts, while resisting leakage.

One important feature of the anvil malleable iron unions is that the union has thicker walls, which is why they can withstand higher pressures than class 150 fittings. The Anvil Model malleable iron union dimensions are designed and well suited for  applications in industries such as air, water, oil, natural gas, and steam.


What is ASME B16.39 Union?


ASME B16.39 Malleable Iron Union

The Standard for specification ASME B16.39  covers threaded malleable iron unions. The ASME B16.39 Union includes pressure ratings for classes 150, 250, and 300 in the specification. It also contains provisions for those manufacturers using steel for NPS 1/8 unions. This Standard includes requirements for design, size, marking, materials, joints and seats, threads, hydrostatic strength, tensile strength, air pressure test, sampling, coatings, pressure as well as temperature ratings,  and dimensions.
